' SHEET 5 0F 7 INVENTORS KARL M. MURGAS BURTON GREENBERG BY OTTO A.CLARK AT TORN Er COMBINATION SHEET AND BOOK COPY MACHINE BACKGROUND OFTHE INVENTION The present invention relates generally to photocopydevices, including electrostatic photocopy devices, for reproducing anoriginal document sheet or book, and more particularly relates to asingle photocopy machine capable of being converted from a book copierto a rapid cycle sheet copier or from a rapid cycle sheet copier to abook copier.

Still more particularly, the invention relates to a single machinehaving the capability to provide original document book copying andrapid cycle original document sheet copying, and to reproduce theoriginal document onto a length of sensitized paper automatically pulledfrom a roll supply or unto a sheet of sensitized paper manually insertedinto the machine.

Electrostatic photocopy devices are commonly constructed to pass aspecially coated and electrostatically charged sheet of copy paperthrough the focal plane of an optical conversion system. The originaldocument to be copied is positioned before the objective camera lens.The image of the document is transferred through the optical camerasystem and onto the sensitized surface of the copy paper. The exposed orsensitive surface of the copy paper is then passed through a fluidsuspension of ink particles suitably charged to react with theelectrostatically charged image borne upon the copy paper surface.

It is both technically inconvenient and costly to view at one instant anentire original document page through an objective lens of a copymachine camera system in order to transfer at one instant the image ofthe entire document page to the sensitized copy paper. To view at oneinstant an entire sheet of an original document requires anexceptionally wide angle lens and large optical elements havinginconveniently long focal lengths. This arrangement is furtherundesirable by the possible loss of resolution and edge distortion ofthe image transferred to the copy paper. Also, the cost of the opticalcomponents required for viewing a large area instantaneously areappreciably greater than the cost of optical components designed forviewing a relatively smaller area.

Previous photocopy machines avoided designs that require wide angleoptical components, for instance, by passing a movable camera past astationary original document which was positioned on a transparentscanning window. The sensitized paper was held fixed in the camera focalplane and the image were projected onto it in successive increments asthe camera moved past the original document. A movable'camera systemrequired substantial space and mechanical complexity,

and therefore photocopy machines so equipped were likely to be bulky insize, heavy, inherently slow and expensive to own or even lease.Furthermore, the moving camera system was not capable of being rapidlyaccelerated and was required to be returned after each cycle to theoriginal or starting position before the next print cycle could beinitiated.

A lighter, smaller and more rapid print cycle for a photocopy machinemay be constructed if the original document is transported before theobjective lens of the copy machine camera and simultaneously sensitizedcopy paper is moved in the camera focal plane at a direction and speedcoordinated with the changing image transferred through the cameraoptical system.

Previous to the invention herein photocopy machines hav ing a movableoriginal document system and a movable copy paper system were usedprimarily for reproducing documents in a sheet form. When books or otherarticles of substantial thickness were to be reproduced, the copymachines having a movable camera system were generally used.

Recently, a single photocopy machine having a movable document andmovable copy paper system has been used for reproducing sheets andbooks. In these machines, the original document, whether sheet or book,is placed on a movable carriage and covered over with a rubberized heavysecuring pad.

The carriage was transported across the objective lens of the camera.After the document was scanned, the carriage returned to its originalposition.

Since every reproduction required the use of a movable carriage, theoperation of the machine was always slow and time consuming. The subjectinvention overcomes this problem by providing a photocopy machine whichonly requires a sweeping carrier for reproducing a book or other articleof substantial thickness. For reproduction of an original documentsheet, the book copier is easily and simply converted to a rapid cyclesheet copier which does not require a carrier. Since the officetypephotocopy machine would be generally used more for reproducing documentsheets of letter or legal size, rapid cycle performance is provided bythe invention herein, for the major portion of machine operation.

SUMMARY OF THE INVENTION The present invention provides a photocopymachine for reproducing an original document sheet or book. When themachine is used as a book copier, the open page of a book is positionedon a transparent plate of a movable carrier. The carrier moves in aforward direction across a scanning window for reproducing the page.After the page is scanned, the carrier automatically returns to itsoriginal position. Converter means are provided to convert the photocopymachine from a book copier to a rapid cycle sheet copier. When thephotocopy machine is used as a sheet copier, the original documenttransport system conveys the original sheet from an input end across ascanning window to an output end.

The converter means comprises a double hinging means which enables themachine to be easily and simply converted from a book copier to a rapidcycle sheet copier or from a rapid cycle sheet copier to a book copier.

The carrier slides within elongated grooves during its operating cycle.The carrier may be removed from the machine by being lifted out of thegrooves in an upward direction. The carrier comprises trigger means toautomatically control its forward and reverse movement.

Accordingly, a primary object of our invention is to provide a singlephotocopy machine for reproducing an original document sheet or book.

Another primary object is to provide a photocopy machine whereby amovable carrier is used for reproducing a book and means are providedfor rapidly reproducing an original document sheet which does notrequire the use ofa carrier.

Another primary object is to provide a photocopy machine having amovable original document transport system which is convertible from abook transport system to a rapid cycle sheet transport system or from arapid cycle sheet transport system to a book transport system.

Another object is to provide a photocopy machine having hinge means toafford simple and easy conversion of the original document transportsystem from a book transport system to a rapid cycle sheet transportsystem or from a rapid cycle sheet transport system to a book transportsystem.

Another object is to provide a photocopy machine for reproducingincrements of a moving document sheet or book onto a sheet ofphotosensitive copy paper manually inserted into the photocopy machineor onto a length of photosensitive copy paper pulled and severed from aroll of copy paper.

Another object is to provide a photocopy machine capable of providingmultiple copies of an original document sheet or book.

Another object is to provide a photocopy machine having a substantiallylinear pathway for moving an original document past a scanning window.

Another object is to provide a transparent carrier which is removablyassociated with the photocopy machine to transport a book or otheroriginal documents of substantial thickness across ascanning window forreproduction.

Another object is to provide the carrier with trigger means forcontrolling themovement of the carrier in the forward and reversedirections, when reproducing one or a multiple of copies.

Another object is to provide a flexible and transparent sheet holderhaving trigger means to control its forward and reverse movement, foruse when reproducing multiple copies of a sheet document when thephotocopy machine is in a nonbook copying position.

Another object is to provide a photocopy machine which providessimplified pathways for transporting original documents and copy paper.

These and other objects and advantages of the invention will becomeapparent from the illustrations in the accompanying drawings and thefollowing specification and claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the severalFigures of the drawings, the reference numeral 10 indicates generally acombination sheet and book photocopy machine. The photocopy machine 10comprises a substantially rectangular frame 12 having a pair of opposedsidewalls 13 and 14, a front side 15 and a rear side 16. The combinationsheet and book copier 10 comprises an original document transport systemindicated by the designation 18A when the machine 10 is used as a bookcopier (FIGS. 2, 3, 5 and 6) and indicated by the designation 183 whenthe machine 10 is used as a rapid cycle sheet copier, (FIGS. 1 and 4), acopy paper transport system 19 and a camera means 20.

With particular reference to FIGS. 10 to 15, a converter means indicatedgenerally by the reference numeral 21 enables the original document booktransport system 18A shown in FIG. 3 to be converted to a rapid cycleoriginal document sheet transport system 188 shown in FIG. 4, or fromthe rapid cycle original sheet transport system 188 to the original booktransport system 18A.

Book Copier Turning now to FIGS. 2, 3, 5, 6, 16, 17 and 22, thecombination book copier and rapid cycle sheet copier machine 10 will bedescribed with greater detail first as a book copier.

The book transport system 18A (FIGS. 2, 3 and 5) comprises asubstantially linear pathway indicated generally by reference numeral 24for transporting a book carrier 25 (see FIGS. 7 and 8) on which a book26 or other article of substantial thickness is positioned, from aninput end 27 to an output end 28 on the platform 22, and back again tothe input end 27.

The book carrier 25 is driven across the pathway 24 from the input end27 an input drive roller 29, drive roller 30 and output drive roller 31.Idler rollers 32 and 33 are rotatably mounted on platform 22, andprovide a smooth transition as the book carrier 25 is transported fromthe frame 12 onto the platform 22.

A transparent glass scanning window 34 is positioned in the pathway 24between drive roller 30 and output drive roller 31. The imagesofincrements of the open page of book 26 moving across the scanningwindow 34 is transferred by the camera means 20 (FIG. 3) onto a lengthof photosensitive copy paper.

The copy paper transport system 19 (FIG. 3) comprises a pathway 35 fortransporting the length of copy paper from a copy paper input end 36 toa copy paper output end 37. The copy paper may be stored on a roll 39supported on a spindle 40, as shown in FIGS. 3, 5, 6 and 17, or may beinserted by individual sheets 41 at the input end 36. The immediatelyfollowing description of the photocopy machine 10 will relate to onlythose machines having the copy paper fed from a rolled supply 39.

The copy paper transport system 19 includes an input pair of cooperatingrollers 42 and cooperating pairs of rollers indicated respectively bythe numerals 44, 45 and 46. The roller pairs 42, 44, 45 and 46 arespaced apart within the pathway 35 and move the copy paper from theinput end 36 to the output end 37.

An image receiver section 48 (FIG. 3) is positioned in the copy paperpathway 35 between roller pairs 44 and 45. The image of the open page ofthe book moving across the scanning window 34 is conveyed by the camerameans onto the length of photocopy paper moving across the imagereceiving section 48. Section 48 may be a ladder-type configurationformed from a nylon material, having a rectangular outer perimeter andspaced-apart cords extending from one elongated side to the other, orother suitable configurations may be used which do not affect thesharpness or definition of the transferred image of the originaldocument. A backup plate 49 is opposed to and spaced from the imagereceiving section 48. The copy paper moves between the backup plate 49and the section 48.

A knife means (FIG. 3) indicated generally by the reference numeral 50is positioned in the copy paper pathway 35 inward from and adjacent tothe input pair of rollers 42. After the book carrier has passed over thescanning window 34, the knife means 50 is actuated and severs the lengthof copy paper from the roll 39. Knife means 50 is only used when thecopy paper is pulled from a rolled supply.

A corona section indicated generally by the reference numeral 52 (FIG.3) is positioned between the knife means 50 and roller pair 44. Coronasection 52 charges or sensitizes the photosensitive paper prior to itspassage across the image receiving section 48.

After the camera means 20 has transferred the image of the open bookpage onto the photosensitive copy paper, the exposed copy paper thenpasses through a receptacle 53 containing toner solution 53 (FIG. 3).The receptacle 53 has a toner overflow section 55 which collectsdrippings from roller pair 46. The toner solution develops the exposedcopy paper. The output pair of rollers 46 transfers the copy paper to anoutput conveyor 56 leading to the copy paper output 37. Although variousoutput conveyors may be used, conveyor 56 comprises a plurality ofrevolving spaced-apart flexible O-ring members 56.

Referring now particularly to FIG. 6 of the drawings, the mechanicaldrive means for the book transport system 18A and copy paper transportsystem 19 will be described. A main motor 58 (FIGS. 6 and 21) drives amain continuous revolving drive chain 60. The main chain 60 drives theinput drive roller 29 of the book transport system 18A and the driverollers 62, 63, 64 and 65, respectively, of rollers pairs 42, 44, 45 and46 of the copy paper transport system 19 (FIG. 3). The idler rollers ofroller pairs 42, 44, 45 and 46 are designated, respectively, by thenumerals 62, 63', 64 and 65. The idler rollers rotate when thecorresponding drive roller of each roller pair rotates.

A reverse motor 66 drives a reverse continuous drive chain 67 in theopposite direction with respect to the rotation of main chain 60 orcounterclockwise as viewed in FIG. 6. The reverse motor 66 is only onwhen the carrier 25 is returned from the output end 28 back to the inputend 27. During the interval when the reverse motor 66 is on," reversechain 67 drives the drive rollers 29 and and output drive roller 31 inthe counterclockwise direction.

The main chain 60 provides the driving power for transporting thecarrier 25 from the input end 27 to the output end 28 and the lengthofcopy paper from the copy paper input end 36 to the copy paper outputend 37. The reverse chain 67 provides the driving power to transport thecarrier 25 from the output end 28 back to the input end 27.

A copy paper clutch means indicated generally by the reference numeral68 (FIGS. 6, l9 and 21) couples and decouples the main drive chain 60from the drive roller 62 of copy paper input roller pair 42. The clutchmeans 68 may comprise a rectifier means 68a (FIG. 21) to convertalternating current, AC, power to direct current, DC, power forenergizing an electromagnet 68b enclosed within a housing 69. Thehousing 69 with the electromagnet 68b is mounted on a shaft 70 of thedrive roller 62 of the input roller pair 42. The rectifier means 68a maybe mounted at a convenient location on one of the sidewalls of the frame12. The energizing of the electromagnet 68b mechanically links the shaft70 with a sprocket 72 (FIG. 5).

The teeth of sprocket 72 (FIG. 5) engages the main drive chain 60.Normally, the electromagnet 68b is energized and sprocket 72 is lockedto the input drive roller 62, causing input roller pair 42 to rotate asthe sprocket 72 is rotated by the main chain 60. After the knife means50 has severed the length of copy paper from the copy paper roll 39,electromagnet 68b is deenergized to mechanically decouple the copy paperinput roller pair 42 from the main chain 60. This prevents any furtherfeeding ofcopy paper into the copy paper pathway.

A document clutch means indicated generally by the reference numeral 73(FIGS. 5, 6 and 22) couples and decouples the main chain 60 from theinput drive roller 29. Clutch means 73 may also comprise a rectifiermeans 73a to convert alternating current, AC, power to direct current,DC, power for energizing an electromagnet 73b (FIG. 21) enclosed withina housing 74. The energizing of the electromagnet 73b mechanicallycouples a shaft 75 of the book input roller 29 to a-main sprocket 76.The teeth of sprocket 76 engage the main drive chain 60 (FIGS. 5 and 6).During the forward movement of carrier 25, the electromagnet 73b isenergized and the sprocket 76 is locked to the input roller 29, causingthe input roller 29 to rotate as the sprocket 76 is rotated by the mainchain 60.

An auxiliary sprocket 77 (FIG. 5) is fixedly fastened on the shaft 75 ofthe document input roller 29. The teeth of sprocket 77 engage thereverse chain 67. When the document input drive roller 29 is driven bythe main chain 60, which is when the reverse motor 66 is of auxiliarysprocket 77 is simultaneously rotated to drive the reverse chain 67 inthe forward direction or clockwise as viewed in FIG. 6, which is thesame direction as the movement of main chain 60. The forward movement ofthe reverse chain drives drive roller 30 and output drive roller 31 inthe forward direction. After the carrier 25 has reached the output end28, the electromagnet 73b of document clutch means 73 is deenergized andreverse motor 66 is turned on. The deenergizing of the electromagnet 73bof document clutch means 73 mechanically decouples the document inputdrive roller 29 from the main chain 60. When the reverse motor 66 isturned on," the reverse chain 67 drives the documentdrive rollers 29, 30and 31 in the reverse direction or counterclockwise, which is oppositein direction to the rotation of main chain 60, causing the carrier 25 toreturn to the input end 27.

The camera means 20 (FIG. 3) comprises a reflecting mirror 78 positionedto receive the images of the open page of the book or other documentmoving across the scanning window 34 and reflects the images into thefocal plane of an objective lens 79.

The objective lens 79 focuses the images of the book through an imagepathway 79' and onto the photosensitive copy paper moving across theimage receiving section 48. Light is beamed to the mirror 78 by a highintensity lamp 80. As shown, the image pathway from the mirror 78 to theimage receiver section is substantially parallel with respect to theoriginal document pathway 24 and extends toward the rear side 16 ofthemachine.

With particular reference to FIGS. 3, 5 and 21, the control switchingcircuitry will be described. A'control switch 81, SW1 is centrallypositioned inward from document drive roller 29. Switching arm 81' (FIG.21) of control switch 81, SW1 is switchedyfrom a normal or off-positionto an on-position by the leading edge 82 (FIGS. 7 and 8) of the carrier25.

In the on-position, control switch 81, SW1 causes the energizing of theelectromagnet 68b of the copy paper clutch means 68 and the energizingofa relay 83 (FIG. 21) which sets a knife solenoid 83 of knife means 50in a go or ready condition.

Relay 83 includes a switch 83A and a switch 83B (FIG. 21 Switch 83Aprovides an electrical connection to line 2 voltage for knife solenoid83', when relay 83 is energized and switch 81, SW1 is in itsoff-position. Switch 83B provides an electrical connection to line 2voltage for energizing clutch means 68 and maintaining relay 83energized after it is initially energized when switch 81, SW1 moves fromits off-position to its on-position. Relay 83 and clutch means 68 remainenergized until the knife means 50 has severed a length of copy paperfrom roll 39.

An exposure switch 84, SW2 (FIGS. 3 and 21) is positioned adjacent theinput to the corona section 52. The leading edge of the copy paperswitches the exposure switch 84, SW2 from a normally off-position to anon-position. When switch 84, SW2 is in the on-position, a relay 85 (FIG.21) is energized which closes relay switch 85'. Switch 85 in the closedposition connects line 2 voltage to a high voltage power supply 86 andthe high intensity lamp 80; thereby turning on the high voltage supply86 and energizing the high intensity lamp 80. Power supply 86 supplieshigh voltage to the corona section 52 to sensitize the copy paper as itpasses through.

A hold switch 87, SW3 (FIGS. 3 and 21) is positioned in the copy paperpathway 35 between the image receiving section 48 and roller pair 45.The hold switch 87, SW3 is switched to an on-position from a normallyoff-position by the leading edge of the copy paper. Hold switch 87, SW3remains in its on-position and maintains the lamp 80 and high voltagepower supply 86 on" until the entire length of the severed copy paperhas moved past the image receiving section 48. After the trailing edgeof the copy paper travels past the hold switch 87, SW3, the hold switchreturns to its off-position and lamp 80 and power supply 86 turn of Thecontrol switch 81, SW1 automatically returns to its offposition afterthe trailing end 88 of the carrier 25 (FIGS. 7 and 8) has moved past andthereby causing line 2 voltage to be connected to the knife solenoid 83through switch 83A. The solenoid 83 becomes energized, which activatesthe knife means 50, whereby a leng h of copy paper is severed from theroll 39 having substantially the equivalent length as the carrier 25.

The cutting action of knife means 50 open switch 89 (FIG. 21) causingthe deenergizing of the electromagnet 68b of the copy paper clutch means68 and the deenergizing of relay 83 by severing their electricalconnection with line 2 voltage.

Referring to FIGS. 7 and 8, the carrier 25 comprises a transparent plate90 secured within an elongated holder 91. The plate 90 is formed from anonscratchable material such as glass. The holder 91 comprises an uppersection 91' ofa lower section 92. The forward edge or shoulder 92' ofthe lower section 92 is spaced inward from the front end 82 of thecarrier 25. A substantially L-shaped trigger finger 93 extendsperpendicularly outward from the holder 91 adjacent the trailing end 88of the carrier 25. The lower section 92 and finger 93 provided triggermeans to control the forward and reverse movement of carrier 25.

An outer grooved track 94 (FIGS. and 16) extends lengthwise along thetop of the machine adjacent side 14 from input end 27 to output end 28.The width of outer track 94 is slightly larger than the width of triggerfinger 93.

An inner grooved track 95 is adjacent the outer track 94 and alsoextends lengthwise along the top of the machine from the input end 27 tothe output end 28. The width of inner track 95 is slightly larger thanthe width of the lower section 92. When the carrier 25 is operatively inplace, the trigger finger 93 is positioned in outer track 94 and lowersection 92 is positioned in inner track 95. The finger 93 and lowersection 92 slide within their respective tracks 94 and 95 as the carrier25 moves in forward or reverse direction. The carrier 25 is removed fromthe machine by lifting it upwardly and out of tracks 94 and 95 Areverse-control relay 96 controls the voltage applied to the reversemotor 66, to the document clutch means 73 and to control switch 81, SW1.Relay 96 includes a relay switch 97 and a relay switch 98. In thedeenergized condition for relay 96 as shown in FIG. 21, movable arm 99of relay switch 97 contacts terminal 102 and movable arm 104 of relayswitch 98 contacts terminal 106. Terminal 106 is connected to theswitching arm 81' of control switch 81, SW1. When relay 96 is energized,movable arm 99 of switch 97 contacts terminal 108 and movable arm 104ofswitch 98 contacts terminal 110.

A switch 112, SW4 (FIGS. 5 and 21) is positioned in the inner trackadjacent the input end 27 for the original document. Upon contact of theforward edge 92' of carrier 25 with switch 112, SW4, the movable arm 114connects with terminal 116, which in turn is connected to movable arm104 of relay switch 98 of relay 96. As may be seen from FIG. 21, line 2voltage from switch 112, SW4 is applied to switching arm 81' of controlswitch 81, SW1 through switch 98 when relay 96 is in the deenergizedstate. Switch 112, SW4 is maintained on" until the entire length oflower section 92 of the carrier 25 has passed over.

A manually controllable double-pole, double-throw switch indicatedgenerally by numeral 117 (FIGS. 1, 2 and 21) and having a single copyposition and a multiple copy position, is mounted on sidewall 14. Switch117 includes a switch 117A and a switch 117B. For the presentdescription of the book copier, switch 117 will be considered in itssingle copy position as shown in FIG. 21.

A hold switch 118, SW5 (FIGS. 5 and 21) is positioned in the inner track95 adjacent document drive roller 30. The forward edge 92 of the lowersection 92 of carrier 25 mechanically switches 118, SW5 from a normallyoff-position to an onposition by forcing the movable arm 120 intocontact with terminal 122. Terminal 122 is connected to terminal 116 ofswitch 112, SW4. When switch 118, SW5 is switched on," switch 112, SW4is also on. When the trailing end 88 of carrier 25 finally passes switch112, SW4, the hold switch 118, SW5 provides line 2 voltage to thecontrol switch 81, SW 1.

A switch 126, SW6, (FIGS. 5 and 21) is positioned in the outer track 94also adjacent drive roller 30. Trigger member 93 moves switch 126, SW6to an on" position from a normally off" position, whereby its movablearm 128 contacts terminal 130 which is connected to line 2 voltage.Movable arm 128 is connected to terminal 132 of relay 96. The otherterminal 1340f relay 96 is connected to line 1 voltage. Therefore, inthe on-position for switch 126, SW6, relay 96 is energized, causingmovable arm 99 of relay switch 97 to move from its off-position incontact with terminal 102, to its onposition in contact with terminal108, and movable arm 104 of relay switch 98 to move from itsoff-position in contact with terminal 106, to its on-position in contactwith terminal 110.

The movement of arm 99 of switch 97 away from terminal 102 severs line 1voltage from the document clutch means 73, causing drive roller 29 to bedecoupled from the main chain 60. The contacting of arm 99 with terminal108 connects line 1 voltage to the reverse motor 66, thereby turning thereverse motor 66 on." Reverse chain 67 now rotates in a counterclockwisedirection as viewed in FIG. 6, driving document rollers 29, 30 and 31 inthe reverse direction.

The movement of arm 104 of switch 98 away from terminal 106 removes line2 voltage from control switch 81, SW1. This prevents the electromagnet68b of the copy paper clutch means 68 from being energized when thetrailing end 88 of the carrier 25 switches the switch 81, SW1 back toits on-position, during the reverse movement of carrier 25 toward theinput end 27. The contact of arm 104 with terminal 110, which isconnected to terminal 132 of relay 96, maintains line 2 voltage on therelay 96 when switch 126, SW6 returns to its off-position after triggermember 93 has passed over the switch in the reverse movement of carrier25.

In the reverse movement of carrier 25, switch 112, SW4 is switched backto its on-position by the lower section 92 of carrier 25 prior to switch118, SW5 returning to its off-position. Thus, switch 112, SW4 connectsline 2 voltage to arm 104 of switch 98 to maintain relay 96 on" afterswitch 118, SW5 returns to its off-position. Switch 112, SW4 returns toits offposition, after the trailing end 88 of carrier 25 moves past, andthereby removes line 2 voltage from relay 96. Relay 96 becomesdeenerized, causing the reverse motor 66 to turn off" and the line 2voltage to be connected to arm 81' of the control switch 81, SW1. Afterthe carrier 25 passes switch 112, SW 1, it stops moving. The machine isnow ready for another operating cycle.

In the single copy position of the single multiple copy switch 117, theelectromagnet 73b of the document clutch means 73 is energized whenswitch 112, SW4 is in its on-position and switch 9? of relay 96 is inits off-position. Therefore, electromagnet 73b is only on" for theforward sweep of carrier 25.

Operation of Book Copier Turning now particularly to FIGS. 2, 3. and 6,the sequence of the operating cycle for the machine 10 will be describedwith greater detail. The operating cycle comprises a photocopy part anda reverse part. In the photocopy part of the operating cycle, thecarrier 25 moves from the input end 27 to the output end 28 and the openbook positioned on the carrier is scanned as it passes the scanningwindow 34, The images of the open book are reproduced onto the length ofphotosensitive copy paper by the camera means 20. In the reverse part ofthe cycle, the carrier 25 is automatically returned to the input end 27of the machine. The switches controlling the sequence of the operatingcycle are all shown in their normally off-position in the variousFigures of the drawings.

The carrier 25 is placed on top of the machine 10 whereby the lowersection 92 is positioned in track 95 and trigger finger 93 is positionedin track 94l, FIG. 16, The carrier is locked in the lateral directionbut may be freed from the machine by merely lifting it in the upwarddirection.

After the electrical power to the machine is turned on," the automaticoperating cycle begins when the carrier 25, with the open book thereon,is manually moved onto the input document drive roller 29 and switch112, SW 1 is switched to the on-position by the forward edge 92' of thelower section 92 of the carrier. Switch 112, SW4 in its on-positionprovides line 2 voltage for movable arm 81' of control switch 81, SW1when switch 98 of relay 96 is in the off-position (FIG. 21 and alsoprovides line 2 voltage for document clutch means 73 when the singlemultiple copy paper switch 117 is in the single position.

The leading edge 82 of the carrier 25 moves control switch 81, SW1 toits on-position whereby line 2 voltage is connected to the electromagnet68b of copy paper clutch means 68 and to relay 83. The electromagnet6812 becomes energized caus ing clutch means 68 to mechanically coupledrive roller 62 of the input roller pair 42 (FIG. 5) with the main chain69. Roller pair 42 pulls copy paper from roll 39 into the copy paperpathway 35. Relay 83 also becomes energized and switch 83A and switch83B moveto their respective on-positions. Switch 83A in its on-positionplaces the knife solenoid 83' in a standby position. Switch 838 in itson-position provides a hold voltage (line 2) to maintain relay 83energized when control switch 81, SW1 returns to its off-position afterthe trailing end 88 of the carrier has passed over. Relay 83 remainsenergized until after knife means 50 has completed its severingoperation.

The leading edge of the sensitized copy paper switches exposure switch841, SW2 on" prior to reaching the corona section 52. In the on-positionfor the exposure switch 841. SW2, relay 85 is energized causing the highintensity lamp 80 and high voltage power supply 86 to turn on." The copypaper passes through the corona section 52 where it is sensitized. Theimages ofthe open book moving across scanning window 34 are transferredby the camera means onto the sensitized copy paper moving simultaneouslyacross the image receiving section 49 at substantially the same rate ofspeed.

The leading edge of the exposed copy paper turns the hold switch 87, SW3to its on-position after passing across the image receiving section 48.When the trailing end 88 of the carrier 25 moves past the control switch81, SW1, the control switch returns to its off-position and provides aconnection to line 2 voltage through switch 83A of relay 83 (which isenergized) for knife solenoid 83. Knife solenoid 83 becomes energized,causing knife means 50 to sever a length of copy paper corresponding tothe length of the carrier 25.

The cutting action of knife means 50 (FIG. 3) opens switch 89 (FIG. 21)which breaks the electrical connection of line 2 voltage with theelectromagnet 68b of clutch means 68 and relay 83. The electromagnet 68band relay 83 become deenergized. Clutch means 68 decouples the driveroller 62 of input roller pair 412 from main chain 60 and thereby stopsany further movement of copy paper from the roll 39 into pathway 35.

The forward edge 92 (FIGS. 7 and 8) of the lower section 92 of carrier25 turns switch 118, SW5 (FIG. 21) to its onposition. At the sameinstant, switch 112, SW4 is held in its on-position by the rear portionof lower section 92. Switch 118, SW5 provides line 2 voltage for controlswitch 81, SW1, when switch 112, SW4 has returned to its off-positionafter the entire lower section 92 has passed over, and switch 98 ofrelay 96 is in its off-position as shown in FIG. 21.

At the instant when substantially the entire carrier 25 has passes thescanning window 34, the trigger finger 93 turns switch 126, SW6 to theon-position whereby line 2 voltage is impressed at terminal 132 of relay96 to cause relay 96 to become energized. When this occurs, switch 118,SW5 is still in its on-position.

Switch 97 of relay 96 moving from the off-position to the on-position,breaks the line 1 voltage connection with document clutch 73, wherebyroller 29 is decoupled from the main chain 60. Reverse motor 66 isturned on causing reverse chain 67 to move in the opposite directionwith respect to main chain 60; thereby driving the drive rollers 29, 30and 31 counterclockwise as viewed in FIG. 6. The carrier 25 now movesinto its reverse sweep back to input end 27.

Switch 98 moving from the off-position in contact with terminal 194 tothe on-position in contact with terminal 110, severs the connection ofcontrol switch 81, SW1 with line 2 voltage. Therefore, the movement ofthe carrier 25 across switch 81, SW1 in the reverse part of theoperating cycle, has no effect. Switch 98 in the on-position connectsline 2 voltage from either switch 118, SW5 or switch 112, SW4 toterminal 132 of relay 96, to maintain relay 96 energized when switch126, SW6 returns to the off-position after trigger finger 93 has passedover.

In the reverse sweep of carrier 25, switch 112, SW4 is turned on by therear edge of lower section 92 before switch 118, SW5 has returned to itsoff-position. When the lower section 92 has passed over switch 118, SW5,switch 112, SW4 provides the line 2 hold voltage for relay 96. After thelower section 92 of the carrier has passed over switch 112, SW4, relay96 becomes deenergized and the carrier is at rest at input 27 waitingfor the next operating cycle to begin.

Converter Means Turning now specifically to FIGS. 10 to 15, theconverter means 21 will be described, Converter means 21 enables thephotocopy machine 10 to be quickly and readily converted from a bookcopier machine (FIG. 2) to a rapid cycle sheet copier (FIG. 1). Theconverter means 21 comprises a hinging arrangement pivotally associatedwith a sidewall of platform 22 and the sidewall 13 of main frame 12.Another converter means 21 is pivotally associated with an opposedsidewall 141 of platform 22 and the sidewall 14 of the main frame 12.The following detail description of converter means 21 will refer onlyto the hinging arrangement associated with the framesidewall 13 andplatform sidewall 140.

FIGS. and 11 illustrate the position of the converter means 21 when thephotocopy machine 10 is operative as a rapid cycle sheet copier, andFIGS. 14 and illustrate the position of the converter means 21 when thephotocopy machine 10 is operative as a book copier.

FIGS. 12 and 13 show the converter means 21 in a transitional positionas platform 140 is moved from the rapid cycle sheet copy position to thebook copy position. FIG. 15A illustrates the transitional position forthe converter means 21 as it is moved from the book copy position to therapid cycle sheet copy position. As shown, platform 22 extends outwardfrom the frame 12 when the photocopy machine is used as a book copier,and forms the upper section of the document sheet transport system whenthe photocopy machine is used as a rapid cycle sheet copier.

The converter means 21 comprises a stationary hinge means 142 and amovable hinge means 143. The stationary hinge means 142 is pivotallyassociated with sidewall 13 and a plate 144. The movable hinge means 143is pivotally associated with the plate 144 and platform side 140. Thestationary hinge means 142 is free pivoting and the movable hinge means143 is spring loaded. Thus, when moving from the sheet copier to thebook copier position (FIG. 12) or from the book copier to the sheetcopier position (FIG. 15A), the stationary hinge means pivots first.

An edge 147 of plate 144 abuts a stop pin 148 (FIGS. 10 and 11), whenthe photocopy machine 10 is set for rapid cycle sheet copying (FIGS. 10and 11). The stop pin 148 prevents any further counterclockwise movementof plate 144 and platform 22.

A finger 149 extends perpendicularly outward from the plate 144. Finger149 abuts a side edge 140 (FIGS. 12 and 13) which is recessed inwardfrom the outer main edge 141 ofside 14. The abutting contact betweenfinger 149 and edge 150 initially occurs midway in the rotationalmovement of the platform 22 as shown in FIGS. 12 and 13.

An edge 142 of sidewall 140 ofthe platform 22 abuts or lies injuxtaposition with the edge 150 of sidewall 13 when the platform 22 isin its outward extended position. The contact of platform edge 152 andframe edge 150 prevents any further clockwise movement of platform 22 asviewed in FIGS. 12 and 13.

As shown in FIGS. 12 and 13, an edge 154 of sidewall 140 of the platform22 is spaced from a second recessed edge 155 of sidewall 13 when theplatform is in its transitional position. Edge 155 is recessed moreinward than edge 150. The clearance between edge 154 and edge 155enables platform 22 to rotate uninhibited around the stationary pivotmeans 142 when moving toward the book copier position or toward therapid cycle position.

To convert the photocopy machine 10 from the rapid cycle sheet copiershown in FIG. 1 to the book copier shown in FIG. 2, the platform 22 andplate 144 are pivoted around the sta tionary hinge means 142 in aclockwise direction as viewed in FIGS. 10 to 13, until finger 149 ofplate 144 abuts edge 150 of frame sidewall 13. This is the maximumrotational distance that the plate 144 can be rotated. With finger 149braced against edge 150, the platform 22 is now rotated around themovable pivot means 143 until edge 152 abuts or is opposed to edge 150.Now the photocopy machine is set for book copy operation.

To convert the photocopy machine 10 from the book copier shown in FIG. 2to the rapid cycle sheet copier shown in FIG. 1, the converter means 21is pivoted from the position illustrated in FIGS. 14 and 15 to theposition illustrated in FIGS. 10 and 11. The platform 22 is pivotedaround the stationary hinge means 142 in the counterclockwise directionuntil edge 147 abuts stop pin 148 which is the position shown in FIG.15A. Plate 144 and platform 22 are then rotated around the movable pivotmeans 142 in the counterclockwise direction until reaching the positionshown in FIG. 10. Now, the photocopy machine is ready for rapid cyclesheet operation.

An elongated grooved member 158 (FIG. 1) is rigidly attached to surface159 of the platform 22. A support bar 160 (FIG. 3) is positioned in thegrooved member 159 and locks the platform 22 in the desired positionwhen the photocopy machine is used as a book copier.

The grooved member 158 (FIG. 2), in addition to holding support bar 160in place, also affords a convenient gripping handle when it is desiredto rotate the platform 22 from its closed position or rapid cycleposition in FIG. 1 to the open position or book copier position in FIG.2.

Spaced rod members 162, 162 (FIGS. 2, 3 and 6) are secured respectivelyat their upper ends to opposed ends of the locking bar member 160 (FIG.6) and adjustably secured at their lower ends respectively to sidewalls13 and 14 of frame 12. An elongated slot 163 (FIG. 3) is formed in thelower end of the rods 162, 162'. A securing means indicated generally bynumeral 164 (FIG. 3) may comprise a screw extending through slot 163 anda lock nut 164 securing each rod 162, 162 to the screw at the desiredpoint along the length of the slot 163. The adjustment of the securingmeans affords means to precisely align drive rollers 29, 30 and 31 withidler rollers 32 and 33 and thereby assure smooth movement of carrier 25as it moves from the main frame 12 onto the platform Rapid Cycle SheetCopier With particular reference to FIGS. 1 and 4, the photocopy machine10 operating as a rapid cycle sheet copier will be described.

As may be seen particularly from FIG. 4, platform 22 forms the uppersection of the rapid cycle original document sheet transport system 188.The idler rollers 32, 33 and an idler roller 166 are journaled tosidewalls and 141 of the platform and extend therebetween. Idler rollers32,33 and 166 lie vertically above in juxtaposition respectively withoutput drive roller 31, drive roller 30 and input drive roller 29.

An original document sheet is inserted into the original documentpathway 24 at the input end 27. Rollers 29 and 166 move the documentinwardly whereby the leading edge thereof switches switch 81, SW1 fromits off-position (Shown in FIG. 21) to its on-position, causing the copypaper clutch means 68 (FIGS. 3 and 6) to energize. The energized clutchmeans 68 couples drive power to the copy paper input roller pair 42which causes the copy paper to be pulled from the roll 39 into the copypaper pathway 35.

The original sheet document is conveyed past the scanning window 34, andincrements thereof are reproduced onto the simultaneously moving copypaper as it is transported past the image receiving section 48. Afterpassing the scanning window 34, the original document is dispensed fromthe machine at the output end 28 located at the front side 15 (FIG. 1)of the photocopy machine.

The copy paper transport system 19 and camera means 20 operate the sameas previously described for the book copier photocopy machine.

When the photocopy machine 10 is used as a rapid cycle copier forreproducing a document sheet onto a length of sensitized copy paper,which is automatically fed from the roll supply 39, the dotted sectionof the electrical schematic designated FIG. 21a in FIG. 21 applies. If,instead, the rapid cycle document sheet copier is set up to reproducethe original document onto manually inserted sheets of sensitized copypaper, the copy paper input arrangement in FIGS. 18 and 19 andelectrical schematic in FIG. 22 apply. Similar parts in FIGS. 18, 19 and22 to those in the other Figures of the drawings, are identified by thesame numeral designation with a 0" suffix.

It is within the contemplation of the invention that the manuallyinsertable copy paper sheet input arrangement illustrated in FIGS. 18,19 and 22 are adaptable for use when the photocopy machine is used as abook copier.

13 Copy Paper Input Referring now particularly to FIGS. 17, 18 and 19,the adaptability of the photocopy machine to be used with a roll supply39 of photosensitive copy 62or with manually insertable individualsheets of photosensitive copy paper, will be described.

Roll Feed If a roll supply 39 of sensitized copy paper is used (FIGS. 3and 17), the leading portion of the paper is initially inserted manuallybetween input rollers 62, 26' of roller pair 42 and pulled past theknife means 50 (FIGS. 3 and 17). In the photocopy operation, the knifemeans 50, as previously described, automatically severs the length ofcopy paper from the roll 39. When the photocopy machine 10 is used as arapid cycle sheet copier, the severed length ofthe copy paper is substantially equivalent to the length of the original sheet document. Whenthe machine 10 is used as a book copier, the severed length issubstantially equivalent to the length of the carrier 25.

Turning now specifically to FIG. 20, it will be seen that the roll ofcopy paper 39 comprises a photosensitive outer layer 168 ofaphotosensitive coating and an inner layer ofa backing material 169. Theouter coating layer 168 may be a zinc oxide or the like mixed with asuitable binder substance. The backing material 169 may be a papermaterial being of substantially lighter weight than an equal unit lengthof the outer coating layer 168.

As the copy paper is pulled away from the roll 39, the tendency is forthe coating layer 168 of the copy paper to strain the copy paper in anoutward direction which is in opposition to the inward curling force ofthe length of copy paper pulled from the roll. Thus, the forces tend tocancel each other out. Therefore, by having the heavier coating on theoutside ofthe roll, the reproduced sheets dispensed at the copy paperoutput 37 are substantially straight even when the copy paper is beingpulled from the end of the roll 39 where there is the greatest tendencyfor the paper to curl.

Manual Feed For the manual copy paper sheet feed (FIGS. 18, 19 and 22),the automatic knife means 50 is not used and in its place, a copy paperstand by switch 170, SW8 is mounted. With reference now to FIG. 22, thestand by switch 170, SW8 has a normal-psoition, as shown, for connectingline 1 alternating current, AC, voltage to the copy paper clutch means680 for energizing the electromagnet 6812c, and a stand by position forsevering the AC line 1 connection with clutch means 681'.

When switch 170, SW8 is in the normal-position, the drive chain 600(FIG. 19) is coupled to the drive roller 620 of the copy paper inputroller pair 42c (FIG. 19). In the stand byposition before the originaldocument is inserted into the system, the drive chain 600 is decoupledfrom the drive roller 620 which prevents the copy paper sheet frompenetrating further into the copy paper pathway 350. The stand by switch170, SW8 is switched from the normalposition to the stand by-position bythe leading edge 171 ofthe sheet ofcopy paper. FIG. 19 illustrates theposition of the sheet of copy paper after the leading edge 171 has movedswitch 170, SW8 to its stand byposition.

In the manual copy paper sheet feed embodiment illustrated in FIGS. 18,19 and 22, the sheet of copy paper must be inserted into the machinefirst. The input pair of feed rollers 42c (FIGS. 18 and 19) transportsthe copy paper from the copy paper input end 36: into the copy paperpathway 35c. The leading edge 171 of the copy paper switches the standby switch 170, SW8 from its normal-position to the stand by-positioncausing the deenergizing of the electromagnet 68hr mechanicallydisassociates the drive roller 620 of the roller pair 420 from the drivechain 60c, which instantly stops any further movement of the copy paper.Thus, when switch 170',

SW8 is in stand by-position, the copy paper is firmly and positivelyheld in place by the input roller pair 42. Now, the original documentmay be inserted into the machine at the convenience of the operator.

When the original document is inserted into the photocopy machine 100,its leading edge switches the control switch 81c, SW1 (FIG. 22) from itsnormal or off-position to its on-position. In the on-position forcontrol switch 810, SW1 the electromagnet 6812c of the clutch means 68cis again energized to mechanically couple the drive roller 620 of inputroller pair 420 to the drive chain 600. Now the sheet of copy paper ispulled inward by roller pair 42c and transported through the copy paperpathway 350 at substantially the same speed as the movement of theoriginal document.

The distance from the stand by switch 170, SW8 to the image receivingsection 480 is substantially equal to the distance from the controlswitch 81c, SW1 (FIGS. 4 and 22), to the document'scanning window 34(FIG. 4). Thus, exact reproduction of the document onto a sheet of copypaper is achieved without simultaneously inserting the copy paper withthe document. Hence, the operator is able to first insert the copy paperevenly into the copy paper pathway 35c, and then subsequently, at hisconvenience, insert the original document also evenly into the originaldocument pathway 24 (FIG. 4). In this manner, clear and identicalreproductions of the original documents are obtained. Moreover, by notrequiring simultaneous feeding of the original document and the copypaper, the probability of jamming due to improper feed of the originaldocument into the original document transport system 18A or B and thecopy paper into the copy paper transport system 19 is virtuallyeliminated.

Prior to the copy paper reaching the corona section 52c, the leadingedge of the copy paper switches the exposure switch 84c, SW2 (FIG. 22)from the normal-position to the on-position to cause the high intensitylamp and the high voltage power supply 860 to be turned on (FIG 3). Theleading edge 171 of the copy paper, after passing the image receivingsection 48c, switches the hold switch 87c, SW3 from the off-position tothe hold-position which maintains the high intensity lamp 800 and thehigh voltage power supply 86c on after switch 840, SWZhas returned toits off-position. Switch 870, SW3 remains in the hold-position until theentire document has been reproduced onto the sheet of copy paper. Afterthe trailing edge of the copy paper has past switch 870, SW3, it returnsto its off-position. The sequence of movement of the copy paper until itreaches the copy paper output 37 is the same as previously described forthe book copier.

Although the foregoing description specifies and the drawings illustratethat the copy paper sheet is to be inserted first into the photocopymachine and afterward the original document, it is contemplated that thesame aforedescribed principles of operation are applicable in anarrangement whereby the original document is inserted first and then thecopy paper.

Multiple Copies The photocopy machine 10'may provide multiple copieswhen the photocopy machine is used as a book copier or as a rapid cyclesheet copier. A stepping switch 176 (FIG. 21) is preset from an outsidecontrol 177 (FIGS. 1 and 2) to the number of copies desired for eachoriginal document inserted into the machine. The stepping switch 176comprises a switch member 178 having an on-position and an off-position.

To obtain multiple copies, it is first necessary to manually switch thesingle-multiple switch 117 from its single copy position (shown in FIG.21), to its multiple copy position. In the single copy position ofswitch 117, switch member 178 is bypassed through switch 117A and line 2voltage is connected through switch 1178 to the document clutch means 73when switch 112, SW4 is in its on-position. In the multiple position forswitch 117, switch member 178 of stepping switch 176 is no longerbypassed by switch 117A and line 2 voltage is connected directly to thedocument clutch means 73 through switch 1178.

For multiple copies, switch 117 is set to the multiple copy position,and the number of copies is dialed into the photocopy machine at thecontrol 177 which causes the switch member 178 of stepping switch 176 tomove from the off to the on-position. Switch member 178 automaticallyreturns to its off-position after the last copy of the original has beenreproduced.

In the on-position for switch member 178 of stepping switch 176, line 1voltage is connected to the document clutch means 73 when switch 97 ofrelay 96 and switch 112, SW4 are in their off-positions.

The stepping switch 176 tabulates the copies by decreasing one positioncorresponding to a digit, each time switch 126, SW6 is switched from theoff to the on-position and connects line 2 voltage to terminal 179 ofthe stepping switch 176. In the last reproduction cycle when steppingswitch 178 moves from the one copy position to the zero copy position,switch member 178 moves from its on-position to its offposition. Thissevers the line 1 voltage connection to clutch means 73 when switch 112,SW4 and relay 96 are in their off-positions.

When the photocopy machine 10 is used as a book copier, switch 126, SW6is switched to the on-position by finger 93 and switch 112, SW4 returnsto its off-position after the lower section 92 of carrier 25 passes overupon completion of the return sweep. The carrier 25 stops at input 27 ifall the copies have been reproduced.

If the stepping switch 176 is in any other position than zero copies,line 1 voltage is connected within clutch means 73 through switch member178. This energizes the electromagnet 73b, causing the clutch means 73to couple the drive roller 29 to the main chain 60. Drive roller 29 nowrevolves in the forward direction or clockwise, as viewed in FIG. 5,which causes the carrier 25, if the photocopy machine is used as a bookco pier, to reverse in direction and move in the forward direction tocommence another copy cycle.

A transparent, flexible holder means 182 as shown in FIG. 9 enablesmultiple copies to be obtained when the photocopy machine 10 is usedexclusively as a sheet copier (FIGS. 1 and 4). Holder member 182comprises a pair of opposed flexible faces 183, 183 which are easilyspread apart to receive a document sheet. The faces 1133, 183' aresecured at their inner edges to a holder 184. A substantially L"-shapedtrigger finger 185 extends perpendicularly outward from the holder.

The lower section 186 of holder 184 slides within the inner track 95 andtrigger finger 185 slides withing outer track 94. The flexible faces183, 133' with the document therebetween are inserted at the input end27 and pass between input roller pair comprising drive roller 29 andidler roller 166, the roller pair comprising drive roller 30 and idlerroller 33 and the output roller pair comprising drive roller 31 andidler roller 166 (FIG. 4). As the holder means 182 passes the scanningwindow 34, the document is reproduced. The holder means moves toward theoutput end 28 until the trigger finger 185 switches switch 126, SW6 toits on-position. When this occurs, the holder means 182 reverses itsdirection of movement and returns toward the input end 27.

The lower section 186 of holder 184 and trigger finger 185 functionidentically as the lower section 92 and trigger finger 93 of the carrier25. Therefore, lower section 186 and trigger finger 185 control theforward and reverse movement of the holder means 182 and thus enablemultiple copies to be obtained when the photocopy machine is in itsdocument sheet copy position (FIGS. 1 and 4), m the same manner asdescribed in the foregoing when the photocopy machine is used as a bookcopier (FIGS. 2 and 3).

From the foregoing description and drawings, it should be apparent thata novel photocopy machine 10 has been provided which accomplishes theaforestated objects in an efficient and improved manner. The photocopymachine 10 may be used as a book copier (FIG. 2) and as a rapid cyclesheet copier (FIG. 1). By providing converter means 21, the movablesection 22 is rotatablefrom the rapid cycle sheet copier position(FIG. 1) to the book copier position (FIG. 2), and from the book copierposition to the rapid cycle sheet copier position.

A removable carrier is provided for transporting an original documentbook across the scanning window 34 when the movable section is in thebook copier position (FIG. 2). Pairs of spaced cooperating rollerstransport the original document across the scanning window when themovable section is in the sheet copier position (FIG. 1).
